Police in Manchester, N.H., plan to set up a sound testing booth at Manchester Harley-Davidson to check motorcycles for compliance with state noise and exhaust laws.
Manchester PD says it plans to staff a booth in the dealership's parking lot for three hours Aug. 16 to help motorcyclists find out whether their bikes exceed the state's legal noise limit of 106 decibels.
Police say they won't ticket violators. "This is completely voluntary and for informational purposes only," the police department says.
New Hampshire law 1) bans "straight pipe" exhaust systems, and 2) sets a limit of 106 decibels for motorcycles, to be measured at 2,800 rpm for one- or two-cylinder motorcycles and 3,500 rpm for motorcycles with three or more cylinders.
